Robotic Static Sounds USB Headset

Issue: When using any USB headset or USB audio input device on any Macintosh with any operating system from 10.5.7 to 10.6.1, after about 10-20 minutes of use, all audio from the headset becomes garbled and has a robotic static sound quality.

Tested with: Dozens of different Macintosh Computers over the last 6 months with different USB headsets and microphone input devices.

Reproducable: Yes, via either Garageband, Ventrilo or a number of other software applications that do USB Audio Input

After countless attempts to fix this problem (I make let's plays of video games so staticy audio is a no go for me), I don't think I really found a solution, but a bit of information. I believe it really depends on what type of microphone you are using.


Let me explain, I am using a late 2011 MBP 13 inch i7 running 10.8.3 Mountain Lion. I have two different USB microphones, one of my mics is a pair of Tritton AX 720's (older model) and the other is a pair of SteelSeries Siberia V2 Frost edition. Whenever I use my Trittons (on anything that records audio such as skype, quicktime, camtasia, etc.) after about 5 minutes there is terrible static and I sound like a robot. This is not the case with my steelseries headset, I have never experienced any static problems with them.


Maybe the problem with my Trittons is that they run through a decoder box? But I am not necesarily sure of that.


I can also debunk the USB hub theory, as far as I can tell USB hubs really have no effect on whether your microphone will cause static or not, I get the same results plugged into a hub as I do plugged directly into my MBP. The results are the same on all of the hubs I own (An HDE 4 port hub, a Targus 4 port hub, and my cooler master laptop cooler has a hub as well).


Changing settings in audio midi also has no effect for me.


All in all, I believe that certain USB microphones sound crystal clear on mac, as others have difficulties and cause static.


Also I do have a question, If I were to get windows 7/parallels and were to run windows, would the static problem persist when I am on the windows partition running things like skype?

MrSantana,


TLDR: yes, it will work without a problem.


The way it works is on a Mac is:

device --> Kernel space (including the .kext modules) --> published device to applications


In Windows, it works exactly the same way:

device --> Kernel space (including drivers) --> published device to applications


Windows might add some additional layers after, but that is irrelevant now.


What most people complain, and me included, is that if you look at that map I just made above, the problem all started back in 10.5, when they changed the USB architecture and some headsets stopped working from before to after patch, and that is why we believe they (Apple) could fix the USBAudio modules.


What you'll notice, if you install windows in a VM or directly through bootcamp, is that the static noise is not reproduced there. Through a VM, you have to choose to plug the USB device only to the VM, otherwise it won't work properly.

Hey all if you really want to fix this problem once and for all buy a Creative usb sound card. All their sound cards have mac software and the robot sound does not happen. Also works with any microphone.

Wow, have a brandnew iMAC late 2013 model and was having so much problems with my Sennheiser DW office headset. I actually have two of them and they both have the same issues as described. However it looks very random. But whatever the case, it always starts after 5 minutes (when it starts).


First we thought it was Skype but when changing to the integrated omni mic everything worked fine again.


I can not change any settings for this device in the midi tool. Very frustrating.... So after all the issues with their crappy Mail, the audio is having issues too. Its a shame.


Good thing I found this thread, i was going crazy and about to invest another 300 euros for a new headset. That would have been 900 euros just to get this piece of crap working...

I have the exact issue with the late 2013 iMac.

I had a late 2009 model with Mavericks installed and a Samson Meteor Mic attached to it. Never had any trouble with the mic. Until I got the late 2013 model and made a fresh install of OS X Mavericks. Now I always get these alien sounds.

I'm making test audio recordings with Quicktime where I have then recorded these aliens sounds.

I am also encountering this symptom on a brand new MBPro Retina 15" w/latest 10.9.2 OSX. I am using a SteelSeries V2 headset, which comes with its own USB dongle.


This wasn't a problem on my older Macbook pro, because it had a Mic In port, but the new one no longer has that port, for what reason, I do not know. So now, the only way to use a microphone (other than the built-in one), is to connect it via USB.


I suppose I will open up a support case, refer to this thread, and see what happens.

ptoal,


Did you know that Apple has been using 4 pin connectors for iMacs and MBPs for at least 4 years?


Basically, all you need is an adaptor, and the MBP does have a mic in, just not in the traditional "PC" way.


All you need is one of these:

I have one, and use it on my iMac late 2009 and used on my MBP too, as well as iPhone, iPad, you name it.

Jul 14, 2014 5:08 PM in response to morph21

Thank you morph21 - I didn't know that - I will try it out!


My whole family uses Mac and i can confirm the problem on

Macbook Air 13" Mid 2014

Macbook Pro 15" early 2011

Macbook Retina 15" mid 2012

Macbook Retina 15" late 2013

iMac 27" late 2012


using MacOS 10.6, 10.7, 10.8 till 10.9.4. Robotic sound @Skype, @Teamspeak and @Ventrilo


I tried 4 different usb-sound adapters. Same issue in all cases.

I haven't solved this issue yet, but I had to login just to say THANK YOU. I have been having this problem across more macs and headsets than I care to admit. I blamed literally every part of the chain except apple. I have used (and spec'd hundreds of thousands of dollars worth of) their production gear professionally for so many years I just trusted them.


I wondered what would make all my conversations start out with "wow, that's great audio you have on your end!", only to end up 5 minutes later with "uhhh, your voice just fell off the ledge there, you must have a network issue. we'll talk later". I am so angry at this moment but also relieved. So, thank you for this slice of voip sanity.

If your Mac ports are USB 3.0 this may help:


I’ve got a solution that may help some but not others. I have a 2010 MacBook Pro and a 2012 iMac and I noticed that, with two different microphones, I was having the robotic voice problem when using my iMac (the MacBook Pro has always worked perfectly). After trying to run the USB through different cables, I plugged my headset through a (non-powered) USB 2.0 hub and the problem was resolved.


I’ve since checked some different message boards and, apparently, there is a compatibility issue with the software when using a USB 2.0 headset with a USB 3.0 port. I cannot confirm this, I can only confirm that the USB 2.0 hub eliminated the issue for me.

Glad I finally found this discussion. I've been having this problem for years with a Plantronics adapter. It'd go robotic after about 46minutes, without fail. Lost that and got a cheapy replacement which only lasted ~8min before going robotic, and that was bad enough to force me to find a solution. In learning that the Griffin iMic doesn't have the problem (and knowing I'd had problems with the C-Media versions, both with my Plantronics and with the new one), I wanted try something else. Nothing against the iMic, but it looked big, and it's also just so old.


The Dragon voice recognition communities seem to be a good source for finding out about reliable hardware, and I learned about the Andrea Electronics USB-SA-1 (link to Amazon, currently $31), so I decided to try that. I just did an hour long video call without going robotic, which is better than I've ever had before. I'll update this post if I have longer calls (which I don't generally), but it looks like the Andrea Electronics USB headset adapter might be another good option.

Six years have passed since this thread was started. My "new" (well, its almost a year old now) imac still have the same issue, and Apple is making it quite obvious that they don't give a ****. If a specific brand of PC´s would handle issues the same way, they would go out of buisness quite soon. But since the AppleCult (myself included), seems completely brainwashed we still buy the ****. Next time i will invest the same amount of money that the Apple **** costs, into a PC, and it will be faster - this **** won't be a problem and when i get issues, they will get fixed with new drivers! I will face the occasional crasch, blue screen and having to update **** by myself with a smile. So long Apple, I've invested way too much in this ****, i will not ever make the same mistake again.
